Blue Sky Combo Duo

The Blue Sky Combo Duo combines the typical clear, articulate Glockenklang sound with the easy handling of a bass-combo. Amplifier and speakers are matched in an ideal way, so the powerful, detailed reproduction of even tiny nuances is guaranteed. In fact the Blue Sky Combo Duo is a combination of the Blue Sky head and the Duo 2x10" cabinet. The accurate mechanical construction of the combo allows the same high quality sound reproduction like the use of single components. Increased gain levels provide smooth overdrive.
